This is a new simulation of a rotating disk being illuminated by a stroboscope. You can control the speed of the disk and the frequency of the stroboscope, and see how the white spot on the disk appears. You can check all the cases of stationary appearance and the slow-motion appearance.
If you or your student or child are having difficulties in learning long division, then you will find this simulation comprehensive and instructional, that guides the learner through the process step by step. This application is for long division with remainder. Another application on long division with float quotient is also available in the simulations section.
I created this course and published it on my Moodle platform. Each module is a SCORM package, with a course evaluation survey at the end and a completion certificate.
The course is tracked, and you must successfully complete each chapter to unlock the next one. The course is fully learner-centered.
With this simulation, you can experiment the refraction of light between air and a transparent semi-disk. You can choose the material of the disk from a list of materials. Also, you can determine the index of refraction of the semi-disk when you apply Snell’s law to measurements you take in the simulation.
Elementary math teachers know the importance of this model in teaching the concept of applying distributive property in area model.
The idea is to break one large area (which represents the product of two numbers) into several pieces (products of smaller numbers), then to find the areas of the pieces individually, and finally add to get the area of the whole (the product of the given numbers).
With this comprehensive and realistic-like photoelectric effect experiment simulation, you will be able to illustrate the following:
The variations of the photocurrent versus potential.
The variations of the photocurrent versus light intensity.
The variation of the kinetic energy of the ejected electrons versus the incident light frequency.
It comes with a graph where you can trace each type of variation as you vary the parameters of the experiment.
Plus, you can experiment and discover more with this simulation.
Educational technology is more about strategically leveraging technology to enhance, transform, and even redefine teaching and learning than just merging education with technology. You have to be a strong educator equipped with learning theories, educational methodologies, and statistical analysis in the first place to be a successful educational technologist.
